USE OF ALCOHOL ADDITIVES FOR ECOLOGICAL GASOLINE PRODUCTION

The purpose of this article is to perform research to improve the stability, quality and efficiency of gasoline-alcohol fuel compositions, as well as obtaining high-octane gasolines corresponding to the modern standards with the addition of alcohols and their mixtures to these gasolines. Research methods: The article considers physicochemical methods for studying the stratification of alcohol-gasoline mixtures, determining the water content in them, as well as determining the octane number of alcohol-gasoline compositions. Results: The raw material base and possibilities of bioethanol production in Ukraine as an ecological additive to gasoline and as a way to increase their octane number were studied. Stratification temperatures of alcohol-gasoline mixtures and octane numbers of A-92 gasoline with different alcohol content were determined. Discussion: It is proposed to use higher concentrations of ethanol (bioethanol) in gasoline mixtures more than 40% of alcohol, because it does not require dehydration. It is proposed to use an additional fuel pump, which would work only for mixing the fuel mixture, to prevent stratification of the fuel-ethanol composition during its long-term storage in the car’s tanks.

INTEGRATED ALGORITHM FOR COMPILINGAND ASSESSMENT OF DIRECT ROUTES RESTRICTIONS IN FREE ROUTE AIRSPACE OF UKRAINE

STRUCTURE AND REQUIREMENTS FOR A UNIVERSAL TRAINING DEVICE FOR UNMANNED AIRCRAFT COMPLEXES

The problems of personnel training for the operation of unmanned aerial vehicles have been updated. The differences between the skills and abilities of personnel for manned and unmanned aircraft are highlighted. The widespread types of flight simulators are considered, their features are given. The basic schemes of application of linear and nonlinear mathematical models of formation (formalization) of knowledge, abilities and skills of the personnel taking into account absence / presence of updating of the information in the course of training are substantiated.The basic modes of operation of USL, the universal simulator for training are specified. Emphasis is placed on the fact that USL is a partial case of an automated training management system (ACS), and a block diagram of training with it is given. The tasks that can be solved on a universal simulator and the requirements for software and hardware, automated workplace, digital sound, general software, peripherals, data exchange, digital video, user interface and webbased automated instructions are discussed in detail. The functions and structure of the universal simulator for training unmanned aircraft complex are presented.

COMPLEX SOLUTIONS FOR SUSTAINABLE DEVELOPMENT OF DEGRADED LANDS OF THE KHERSON REGION

The sustainable development is the prevailing approach to the use of natural resource potential. The degraded agricultural areas loose their economic value and raise a wide range of environmental concerns. The Kherson region is one of the most overexploited territories in Ukraine, which is characterized by diverse soil-climatic conditions. It was offered to use these lands for cultivation of energy crops. The comparative analysis demonstrated that algae and rapeseed are the most efficient alternatives which are able to complement each other and form a perspective energy mix.

FUTURE ATCO OFFICERS’ INDIVIDUAL PROFILES FORMING

PHOTOBIOREACTOR FOR MICROALGAE-BASED WASTEWATER TREATMENT

Purpose and Objectives of the Work. This scientific article is devoted to creation of an advanced photobioreactor design for wastewater treatment from biogenic compounds. Research Methods are based on a systematic analysis of theoretical research, synthesis, anology and comparison. Research Results. As a result, the improved photobioreactor design was proposed, in which the application of new elements and connections reduces the required area for its placement, immobilization of microalgae in the working area and, as a result, reducing the working area, the ability to quickly replace the sleeves of the working area, covered with sediment inside, and, as a result, reduce labor costs and downtime of the photobioreactor. Discussion. The problem is solved by the fact that the photobioreactor is made in the form of a transparent flowing rectangular open-topped tank, inside of which are vertically attached to the bottom of the tank by quick-release fasteners transparent flowing flexible hoses, to which at the bottom by means of non-return valves are connected pipelines for wastewater and microalgae supply and tubes for carbon dioxide supply and are connected by means of shut-off valves pipelines for drainage of a mixture of microalgae with residual wastewater, and in the upper hermetic part, where there are valves for drainage of accumulated gases , while the pipeline for the purified wastewater discharge is connected to a guide tray purified wastewater supply inside of a flowing rectangular open-topped tank, and at the outlet of the pipeline for drainage of a mixture of microalgae with residual wastewater is a microalgae separator to separate return and excess biomass. Conclusion. The proposed construction of photobioreactor can have good perspectives to be use in communal services for sewage water purification from biogenic compounds.
